T0 all 'whom 'it may concern.:

Be it known that l, Josnrii JQ PAYNE, a citizen of the United States,residing at Gincinnati, Ohio, have invented a new 'and use-- ful`Improvement in Carbureters, of which the following is a specification.

:My invention relates t0 carbureters of the class adapted to the useoit-motor ilen hicles or for other suitable purposes, and thev objectsof my improvements are to provide positive means for controlling thevolume of air admitted to the mixing chamber in relation to the volumedf admitted thereto for maintaining "he sii-ed proportion of the fuelmixture un .der different demands for quantity; to pro vide means for.controllingr the quantity of the fuel mixture to be admitted'to theexplosion chamber of theengine under different speeds and duties Withoutchanging its quality; to provide means for admitting the air to theinixing'ehamber from opposite directions to a common meeting pointl andperpendicular to the movement of the gas thereto for effecting a morethorough mixture of the fuel ingredients, and to provide simple anddurable construction and. assemblage ot the various members for se-Acuring facility of operation and efficiency of action. Theseobjects maybe attainedin the following describedinanner, as illustrated in theaccompanying drawings,` in which t* lFigure l is a diametrieal "sectionwith broken parts in elevation of Ia carburetei engagement of the pin 6with the annular groove 7 formed in the stein.. Said float chamber is ofthe ordinary construction and operation and is provided with thegasolf-iie jet nozzle 8 to discharge within the hollow stem in the usualmanner. A rotatively adjustable gate 9 serves to control the air inl letopening il formed inthe tubular shank l@ ftl l-t l be" tll l .i o. ie oacom Vi in ie usua maimei.

The mixing chamber 2 which intersects the body is formed with open endsand with similar open slots 13 in its end portions, as shown in Fig. l.Cylindrical caps vlil are rotatively adjustable on the said respective-end portions oi' the mixing chamber and each of them is formed withsimilar longitudinal slots l5 adapted to registenlwith the correspondingslots 13 in the endfwalls of the mixing. chamber. Each of said `caps l'may be formed with a slotted radiallyprojecting arm 5.6 adapted toinovably engage with thecorrespondiiig ends ofthe double crank shaft 17which may be journaled in bearings lsecured on the body andparal lel.with the mixing chamber-as shown in Fig. 3. Said shaft is provided withyan arm 1 9 whereby it may be adjusted/with theft-aps simultaneously" tolaterally control the width of the slots 13 for admitting more or 1 lessair to the interiorof the mixing chamber in proportion to the amount ofgasolene admitted thereto from ythe jet nozzle 8. i A tubular gate valveQ1 isslidable longitudinally within the cylindrical mixing chamber bylmeans of the rod 22, and is formed with an open end :and near itsopposite end with longitudinal slots 24 ada )ted to reister with thecorres ondine r, Y n.

slots 13 in the vVall of the mixing chamber.'l

Saidvalve is also formed with'a longitudinal opening 25 fortheAfi-e'epassage, therethrough at all tunes of the carburetedai'r fromthe jetnozzle to the interior ofx said valve and also with ,a circularopening 2G to admit iiioie or'lessofthe fuel mixture therefrom to4 thedischarge opening of the body. The longitudinal movement ot said valveis limited and its rotative movement prevented by means olf the movableengagement of the fixed pin 27 with the longitudinal slot 28 formed inits side wall.

Separate actuating connections l (not shown) and placedconveniently'accessible to the operator may be made with the gate valve, the crankshaft and with the adjustable gate E).

ln operation, the rotative adjustment of the caps nl ay serre to controlthe width of the air'inlet slots l?. formed through the ivall -ofthemiiiingf chamber for controlling the proportion of a'r in relationto' the amount of carhureted airr to said chamber for changing thequality of the fuel mix- To thosevskilled in the' art the many adlvantages is evident of accessible facilities arranged tor separately andpositively con# trolling the quality and also the quantity of the fuelmixture to meet the requirements of different speeds and Valso more orless heavy duty required of the engine.

Having fully described my improvements,

what I claim as my invention and desire to secure by Letters Patent ofthe United States is l. In a carbureter, the combination of a tubularbody formed with a transverse mixing chamber having slotted endportions,

similarly slotted caps iotatively adjustable on said end portions forchanging the width l ofthe slots therein, .a gate valve movablelongitudinally within the chamber for controlling -the ldischargeopening therefrom and for simultaneously changing the length of theslotted openings, separate actuating connectionswith the valve and withthe caps, and a float'chamber provided with a.

`gasolene nozzle terminating within the body beneath the chamber.

2; A carbureter comprising a tubular body formed with a tubular mixingchainber perpenilicular'thereto terminating in a series of longitudinalslots, a correspond? ingly slotted cap rotative] y adjustable thereonand arranged to adjust the width ot' said slots. a gate valve for thebody movable longitudinally within the chamber for changing the lengthof. said slots, separate actuating connections therewith and with thecap, and a gasolene nozzle terminating within the body beneath thechamber.

actuating A carbureter conipi'isiiig a tubular body, a tubular mixingchamber formed transversely thereon and terminating in a series oflongitudinal slots at one end and being formed with a similar series ofslots near its other end, similarly slotted caps rotativel.'Y adjustablethereon for changing the width of said slots, a tubular gate valve forthe body and movable longitudinally within the chamber forsimultaneously changing the length o1 the slots therein, a i'loatchainber provided with a g: solcne nozzle ar ranged to discharge withinthe body beneath the mixing chamber, and separate actuating connectionswith the valve and with the caps.

il. In a carbureter the combination with a tubular body, a float chamberswiveled thereon and provided with a gasolene nozzle arranged todischarge therein, of ,a tubular mixing chamber formed transversely onsaid body above the nozzle and forn'ied'ivith air inlet slots in itsopposite end portions, a tubular gate valve for the body slidablymounted within the chamber and arranged to control the length of theslots therein, independent means for simultaneously adjusting the widthoi' said slots, and separate actuatingr connections therewith and withthe said valve.

In a carblujcter, the combination with a tubular body, a transversemixing chambei' integral therewith and formed withI longitudinal slotsVin its end portions, a gasolene nozzle arranged to discharge within thebody' beneath the chamber, and means for simultaneously adjusting thewidth of the slots, of a tubular gate valve for the body and slidablymounted within the cham bei', said valve being ar aiiged tosimultaneously control the passage through the body and also the lengthof the slots, and

connections therewith.
